Molybdenum, a refractory metal recognized for its excellent strength at high temperatures, its high melting point of 2610oC, and its high resistance to corrosion, serves a definite purpose in the laboratory. This high melting point makes molybdenum excellent for use as vapor deposition boats and dishes. Vessels of molybdenum have also been used for such applications as processing nuclear fuel pellets at temperatures up to 1650oC. In addition, molybdenum crucibles are durable and will withstand repeated rough handling. Molybdenum has the ability to withstand many acids including sulfuric, hydrochloric, hydrofluoric, and most organic acids, as well as many molten materials, such as metals, alloys glasses, compounds, etc. Molybdenum is corroded by alkalis in the presence of oxidants.A modern and comprehensive document on the subject is the second edition of the classic CORROSION BASICS textbook.
